ABSTRACT:
New liquid thickeners for aqueous liquids are obtained by capping a liquid straight chain polyoxyalkylene compound derived from ethylene oxide or ethylene oxide and at least one other lower alkylene oxide by reacting said alkylene oxides with at least one active hydrogen-containing initiator having only one active hydrogen atom. The new thickeners are prepared at a molecular weight of about 1000 to about 25,000 utilizing an alpha-olefin oxide having a carbon chain of about 12 to about 18 aliphatic carbon atoms. Both block and heteric polyoxyalkylene compounds are useful. Alternatively, the new thickeners can be made by copolymerizing ethylene oxide or mixed lower alkylene oxides in the presence of said alpha-olefin oxide. The new thickeners exhibit an unexpected increase in viscosity in aqueous systems as compared with prior art liquid polyether thickening agents. The alpha-olefin oxide modified polyether thickening agents of the invention are useful in both water-based and water-glycol based hydraulic fluids.
